I had two 1:1 interviews by a manager and a senior manager. Felt good about both interviews, no tough questions, conversations flowing well, and I did like both of the interviewers. They kept smiling to me, and so I assumed they liked me as well (You should never assume that).
However, when I almost felt 100% positive, I got a rejection letter. Other than feeling very disappointed, I was a bit pissed by getting the email said " we couldn't offer you the internship at this moment", "please consider to apply a full-time position". Dude, I was applying a full-time position?? Speechless...wondering how much do they care about people? Even to those who didn't win this time, we should always maintain a relationship. That's very important as being public accountants!
I did like a few people in the office and made a really good connection with them, but maybe sometimes a group of nice people doesn't represent the firm's culture. I don't believe I have seen the real face of everybody there.
My suggestion is to keep your options open. Always. And now I am extremely excited about going to the place where really belongs to me!
